Question 1
What happens to a snowman on a warm sunny day?
- 📏It grows taller
- 🪵It turns to wood
- ☃️It melts
☃️ It melts
Hint: Heat turns solid snow into liquid water.
Question 2
Put the water cycle in order. Start with the sun warming the water.
- 🌊Water collects in rivers and oceans
- ☀️Sun warms water and it rises
- ☁️Clouds form
- 🌧️Rain or snow falls
Sun warms water and it rises → Clouds form → Rain or snow falls → Water collects in rivers and oceans
Hint: Warm water rises into the sky, makes clouds, falls as rain, and collects in rivers and oceans.
Question 3
You mix red and yellow paint. What color do you get?
- ⚫black
- 🟠orange
- 🔵blue
🟠 orange
Hint: Mixing materials can make something with new colors. Red and yellow make orange.
Question 4
You add sand to water and stir. What happens when you stop?
- The sand dissolves
- The sand turns to salt
- The sand sinks to the bottom
The sand sinks to the bottom
Hint: Sand does not dissolve, so it settles at the bottom.
Question 5
Hummingbirds drink nectar. They also carry…
- soil
- rocks
- pollen
- water
pollen
Hint: Pollen sticks to them.
Question 6
Rain washes a little soil off a hill every year. This is…
- an eruption
- fast
- instant
- slow
slow
Hint: A little at a time adds up.
Question 7
You build a tower, take it apart and build a bridge. The pieces are…
- the same pieces
- melted
- gone
- new pieces
the same pieces
Hint: Pieces can be used again.
Question 8
Is it a solid or a liquid? Tap an item, then tap its basket.
Sort into: 🧱 solid · 💧 liquid
- 🍎apple
- 📕book
- 🧃juice
- 🍯honey
- 🥄spoon
- 🥛milk
🧱 solid: apple, book, spoon · 💧 liquid: juice, honey, milk
Hint: A solid keeps its shape. A liquid flows and takes the shape of its container.
Question 9
Steam from a kettle is water as a…
- ♨️gas
- 🪨rock
- 🧱solid
♨️ gas
Hint: When water is heated until it boils, it turns into a gas called water vapor.
Question 10
Same material or a new one? Tap an item, then tap its basket.
Sort into: ✂️ same material · 🔥 new material made
- ✈️fold a paper plane
- 🧊melt an ice cube
- 🥕chop carrots
- 🍳fry an egg
- 🍞toast bread
- 🎂bake a cake
✂️ same material: fold a paper plane, melt an ice cube, chop carrots · 🔥 new material made: fry an egg, toast bread, bake a cake
Hint: Cutting, bending, melting and mixing keep the same material. Cooking and burning make something new.
